I almost want one.
The measuring frequency is too low, what do you want to measure?

Aliexpress has this for 109 and it actually might work.

I "almost" want to measure my nostalgia.

Who needs nostalgia when your everyday scope is this. I'll give up my trusty analog scope when they pry it from my dead hands.

If it were a little cheaper, I would buy one just do display lissajous waves all day long.
It would be a nice conversation piece on any lab!

@Joey: I am so jealous! Magnificent scope you got there.

One could actually figure them out without having to translate them.
The button with the Led must be power on.
The three pots on the right of the screen must be intensity, focus and graticule illumination. Fiddling with them will tell you which does what.
The pair of rotary switches are labeled X and Y, those must be the scale.

On the bottom row, there are a pair of pots on the right which have an X. Those must be X position and fine attenuation.

Likewise, on the left two pots have a Y label, again position and attenuation for Y.

The middle pot must be the timebase fine adjustment.

Aliexpress has this for $109.32. It just might be worth it. Plus another$80 to ship it... They also have a CRT Transistor Curve Traces for $1400 plus shipping. #### Audioguru again Joined Oct 21, 2019 4,523 Does the 60 years old Chinese 'scope use vacuum tubes? Are its electrolytic capacitors all dried up? #### tautech Joined Oct 8, 2019 236 Aliexpress has this for 109 and it actually might work. View attachment 224547 Be wary of the claimed max sensitivity on these as when coupled with a 10x probe as we mostly use it becomes quite limiting. #### tautech Joined Oct 8, 2019 236 Came across this and it blew my mind! Single Channel, CRT (not an LCD), 2MHz Oscilloscope. Only$190 to US What a bargain But you have to be able to read chinese... I can only assume they think there is a market for it to still make and sell them.

No BNC connectors for Probes! Truly amazing...
At just 2 MHz BW you can work with just DMM probes. Lots of early old low BW CRO's used banana sockets or binding posts.

I'm not in a position to check what my exactly my scope is, but I have an older CRT oscilloscope myself - analog/digital hybrid I bought about 8 years ago. If my memory serves me correctly, it's a Tektronix 2221A, but I don't exactly remember. Works wonderfully, though if I need to save data I have to use my computer-connected digital scope.
I do find it somewhat shocking that anyone is still manufacturing CRT scopes, though. I could also just be oblivious.
